VEHICLE-WHEEL HUB.

Applcationled November 18, 1916. Seria1`:1\To.l132,147.

To all whom t mayconoern: y

Be it known that I, Louis A.y RYAN, a citizen of the Dominion of Canada, residing at Everett, in the oounty'of 'Middlesex and State of Massachusetts, have invented new and useful Improvements in Vehicle- Wheel Hubs, of which the following isa specification. l .l

The present inventioncomprehends `the provision of ya wheel, and more particularly a hub construction therefor, of that type which be-readily-assembled or disassembled topermit of the replacement of damaged or broken spokes and fellies' without the necessity of iirst removing the tire from the wheel, after which the parts constituting the hub construction may be assembled in a strong and durable manner and with despatch;

A further object of the invention resides vin theprovision of means for automatically lubricating the axle ends, bushings, bearings, and nuts Without removing the`wheel and applying lubrication to such parts@ thereof.

With the above and other objects in view, the invention consists in the novel features, details of construction and combination of parts which will hereinafter be more fully set forth, illustrated inthe accompanying drawing and pointed out in the appended claims.

Figure 1 is an end elevation of a wheel illustrating the hub thereof iu longitudinal section;

Fig. 2 is a detail longitudinal sectional View of the inner half of the hub;

Fig. 3 is a longitudinal sectional view of the outer section of thehub; v

Fig. 4 is a side elevation of the axle removed from the hub;

Fig. 5 is a view of the detachable flanged collar illustrated in section; and

Fig.` 6 is a perspective View ofthe grease cup. f

Fig. 7 is a face view of the flanged collar. A

AReferring more particularly to the accompanying drawing, 5 denotes the rim or felly of the wheel, 6-thehub thereof and 7 spokes'connecting the hub with the felly.

The hub construction here shown comprises an inner section 8 and an outer section 9 adapted for detachable connection with one another.

The inner section. .8 is provided with the Specification of Letters Eatent. Patented July 9, QS.

usual hollowf axle box` 10 terminating at its inner extremity in an externally threaded extension..11. Formed on the exterior portion ofthe box 10l at a point rearwardly of the threaded. extension 111 thereof `is a 'iixedffianged collar 12A provided with spoke sockets 18. The character 141 denotes a removable iiangedl collar -provided with anaxial threaded openinoP 15 for threadedly engaging the Yexteriortln'eadedl extension 11 of the bushing. When the collar is threaded' upon said extension the socket 16 thereof will abut with the socket 13, and serve to detaohably hold the spokes 7 in the sockets of the hub, as clearly shown in the drawing. After the detachable flanged collar 14C is applied or threaded upon the extension 11, the same is prevented against any accidental displacement therefrom through the medium ofthe jam nut 17, which as is obviousv from Fig. 1 of the drawing, is threaded upon the threaded extension 11 of the box lO.

The outermost section 9 is of hollow form, and is provided at a point substantially medially of its length,`with an axial threaded opening 18 in which is threaded the extension 11 of the bushing, thus detachably connectingvthe outermost section 9 to the box .thereof,vis secured within the hub through the medium of a nut 23 threaded upon the threaded extension 22 of said axle,y better shown in Fig. 1 of the drawing. The disk 2a of the axle is brought into Yabutting engagement with the extreme inner end of the inner section 8 of the hub and defined against the disk is a packing 25, the purpose of which will be hereinafter more fully ex- 'Y plained as-the description'of the invention is proceeded with.

Y With this form of hub construction, use is made of means for automatically lubrieating vthe hub and its parts, and to this end the axle 21 is provided substantially throughout its length with a groove 26 in which the lubricant from the grease cup 27 From the foregoing description, taken in connection with the accompanying drawing,

the advantages of construction and the Y method of operation will be readily apparent to those skilled in the art to which the in- Y vention relates, and while I have described lthe principles of operation of the invention, .together with the device which I nowconsiderto ybe the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative,pand that such Vchanges may be made when desired as I'Copies of this patent may be obtained for flanged collar having sockets therein, a sec- Y ond flanged collar having an axially thread eil-opening therein engaging with the screw Y threaded extension and a flange coperating with the before mentioned flange to engage the spokes, an outerv section or sleeve having an interior collar intermediate its ends provided with ascrew threadedopening engaging with the lscrew threaded extension, the end of said sleeve being screw threaded and a nut adapted to engage said screw threads.
